MAGNETO-SPINDLE.

SPECIFICATION forming part of Letters Patent NO. 586,790, dated July 20,1897.

T (0 whom, it 71mg cancer/L:

Be it known that I, ALFRED GARTNER, a citizen of the United States,residing in Paterson, county of Passaic, and State of New Jersey, haveinvented certain new and useful Improvements in Magneto-Spindles; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters of reference markedthereon, which form a part of this specification.

1 5 This invention relates to spinning-spindles for silk, cotton, andother filaments; and its object is to provide such spindles with meansfor overcoming or counterbalancing the strain exerted by the drivingband or belt upon the whirl.

The invention consists in the arrangement of a magnet in close proximitywith the sleeve-whirl of a spindle and opposite the driving means,substantially as will be hereinafter more fully described, and finallyembodied in the clauses of the claim.

In the accompanying drawings, Figure 1 is a side elevation of anordinary spinningspindle provided with my improvements, the

0 rail being shown in section; and Fig. 2, a sectional view on the line0e 00 of Fig. 1.

The base I), which is mounted in the spindlerail to in the usual andwell-known manner, contains step and bolster bearing for the 3 5 spindle0, provided with the sleeve 0 and whirl (Z, the latter in frictionalcontact with the driving band or belt 6, as clearly shown in thedrawings.

From one side of the base Z) projects an arm or bracket f, provided atits upper portion with a sleeve g, arranged substantially horizontal andcarrying a magnet i, secured to and within said sleeve by means of thesetscrew it.

That end or pole of the magnet which is adapted to attract the whirl (Zis cut or formed, as at t", to conform to the shape of the groove in thewhirl d, by which arrangement a greater area of the whirl is subjectedto the attracting force or power of the said magnet.

It must be remarked that the magnet is arranged at or near that portionof the Whirl cl which is engaged by the driving band or belt 6, and thuswill counterbalance the action of the said band or belt-that is to say,the band 5 5 or belt 6 endeavors to pull or draw the whirl d in onedirection, while the magnet Will pull or draw the said whirl in theopposite direction.

It will be manifest that in place of the permanent bar-magnet ahorseshoe-magnet or an electric magnet may be employed, and that theshape of said magnets can be varied and modified without changing thescope of my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination with a base, of a sleevewhirl spindle mounted in saidbase, driving means for operating said sleeve-Whirl spindle, and amagnet carried by said base and in close proximity with that portion ofthe sleeve whirl which is in engagement with the driving means,substantially as and for the purposes described.

2. The combination with a base, of a sleevewhirl spindle mounted in saidbase, driving means for operating said sleeve-whirl spindle,

a bracket or arm projecting from said base, and a magnet adjustablyarranged in said bracket or arm and in close proximity With that portionof the sleeve-whirl which is in engagement with the driving means,substantially as and for the purposes described.

3. The combination with a sleeve-whirl spindle and with the drivingmeans, and of a magnet adj ustably and suitably supported and in closeproximity with that portion of the sleeve-whirl which is in engagementwith 0 the driving means, substantially as and for the purposesdescribed.

4. The combination with a Whirl-driven spindle, of a driving-band foractuating the same, a base for supporting said spindle and a magnetcarried by said base on the side of the spindle opposite to the pull ofthe drivingband, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this17th day of I00 April, 1897.

ALFRED GARTNER.
